Professor Emeritus of Food Safety and Nutritional Sciences, Department of Food Science and Human Nutrition, University of Illinois at Urbana-Champaign

Bruce M. Chassy is a Professor Emeritus of Food Safety and Nutritional Sciences from the Department of Food Science and Human Nutrition at the University of Illinois at Urbana-Champaign.  He served as the Assistant Dean for Science Communications in the College of Agricultural, Consumer and Environmental Sciences and was Head of the Department of Food Science and Human Nutrition at the University of Illinois from 1989 to 2000.  Dr. Chassy completed his undergraduate training in Chemistry at San Diego State University and his Ph.D. in Biochemistry at Cornell University.  He was a research chemist at the National Institutes for Health (NIH) from 1968-1989.  Dr. Chassy was a Fulbright Distinguished Lecturer in Spain in 1994.

Dr. Chassy’s research focused on the characterization and development of methods for the genetic manipulation of microorganisms used in food and dairy fermentations.  His research experiences with the development of genetically modified microorganisms that are used in foods led him to an interest in food safety and the safety evaluation of "biotech foods.” He maintains a website that explores the safety of GM foods at http://academicsreview.org.

A: I understand that claims made by Jeffrey Smith, the movie’s director and author of the self-published book, Genetic Roulette, are alarming and could cause great concern. It’s important to understand Mr. Smith’s background. He is not a doctor or researcher, and he has never conducted a scientific study or published a peer-reviewed scientific paper. Please read his biography at his website to confirm this. He is an energetic, articulate and persuasive layperson who has made himself into one of... Continue Reading

A: In recent years we have become more aware of autism and the suite of neurodevelopmental conditions sometimes called autism spectrum disorder. Medical research is not completely certain about the causes of autism, nor is there a magic pill that “cures” the disorder. On a personal level, this causes me a great deal of anxiety because I have a grandson who has been diagnosed with Asperger’s syndrome, one of the autism spectrum disorders. Although the incidence of autism sounds low when we read... Continue Reading

A: The claim is not substantiated in the Kruger et al. 2014 paper, and no relationship is shown between glyphosate in urine and health. The design, conduct, analysis and conclusions of the research are all so flawed that one wonders how the paper was accepted (in 20 days) even in a journal with a low impact factor (0.6). This is just another in a growing series of flawed papers designed to incite fear. The reasoning that underlies this conclusion is briefly explained in the... Continue Reading

A: For all meaningful purposes, the answer is no, but it’s seldom that simple. Let’s review quickly that the differences in most crops from GM methods and traditional breeding are a protein (1 new protein of 30,000 background proteins) and a gene sequence (on average, 0.0003 percent of the DNA). Notice that I said a “new protein” or “gene sequence,” since proteins and DNA are made of amino acids and nucleotides, respectively. The GM-derived amino acids and A... Continue Reading

A: No! There is no way to detect whether an animal has been fed GM feed because there is no content from any part of the GM feed in the flesh, milk or eggs.  The GM feed is digested and assimilated in exactly the same way as any other feed.  There is in fact no meaningful measurable difference between GM and convention feeds. Actually that's not exactly true.  It turns out that conventional and organic feeds can have more of the mycotoxin fumonisin in them than does insect...
